drm/printer: Allow NULL data in devcoredump printer

2024-10-17T13:08:16+00:00

[ Upstream commit 53369581dc0c68a5700ed51e1660f44c4b2bb524 ] We want to determine the size of the devcoredump before writing it out. To that end, we will run the devcoredump printer with NULL data to get the size, alloc data based on the generated offset, then run the devcorecump again with a valid data pointer to print. This necessitates not writing data to the data pointer on the initial pass, when it is NULL. v5: - Better commit message (Jonathan) - Add kerenl doc with examples (Jani) Cc: Maarten Lankhorst Acked-by: Maarten Lankhorst Signed-off-by: Matthew Brost Reviewed-by: Jonathan Cavitt Link: https://patchwork.freedesktop.org/patch/msgid/20240801154118.2547543-3-matthew.brost@intel.com Signed-off-by: Sasha Levin

drm: drop use of drmP.h in drm/*

2019-05-27T16:07:03+00:00

The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.
